We see Michael Psellus in the 11th Century surprisingly contrasting "the ancient and lesser Rome, and the later, more powerful city" [! It is now hard to grasp Constantinople as a greater city than Rome, but there would have been little in Rome's favor in Psellus' day. Even so, in the midst of Istanbul, it mostly still remains standing, in some places even restored, its breaches merely allowing modern streets to pass [ note ].
The term comes from "Byzantium", the name of the city of Constantinople before it became Constantine's capital.
This older name of the city would rarely be used from this point onward except in historical or poetic contexts. Imperium Romanum, Imperium Romanorum; Greek: Res Publica Romana; Greek: Imperium Graecorum in the West to refer to the Eastern Roman Empire and of the Byzantine Emperor as Imperator Graecorum Emperor of the Greeks  were also used to separate it from the prestige of the Roman Empire within the new kingdoms of the West.
Needing Charlemagne's support in his struggle against his enemies in Rome, Leo used the lack of a male occupant of the throne of the Roman Empire at the time to claim that it was vacant and that he could therefore crown a new Emperor himself.
History of the Byzantine Empire Early history The Baptism of Constantine painted by Raphael 's pupils —, frescoVatican City, Apostolic Palace ; Eusebius of Caesarea records that as was common among converts of early Christianity Constantine delayed receiving baptism until shortly before his death  The Roman army succeeded in conquering many territories covering the entire Mediterranean region and coastal regions in southwestern Europe and north Africa.
These territories were home to many different cultural groups, both urban populations and rural populations. Generally speaking, the eastern Mediterranean provinces were more urbanised than the western, having previously been united under the Macedonian Empire and Hellenised by the influence of Greek culture.
This distinction between the established Hellenised East and the younger Latinised West persisted and became increasingly important in later centuries, leading to a gradual estrangement of the two worlds. Byzantium under the Constantinian and Valentinian dynasties To maintain control and improve administration, various schemes to divide the work of the Roman Emperor by sharing it between individuals were tried between andfrom tofrom toand again between and Although the administrative subdivisions varied, they generally involved a division of labour between East and West.
Each division was a form of power-sharing or even job-sharingfor the ultimate imperium was not divisible and therefore the empire remained legally one state—although the co-emperors often saw each other as rivals or enemies.
Inemperor Diocletian created a new administrative system the tetrarchyto guarantee security in all endangered regions of his Empire. He associated himself with a co-emperor Augustusand each co-emperor then adopted a young colleague given the title of Caesarto share in their rule and eventually to succeed the senior partner.
The tetrarchy collapsed, however, in and a few years later Constantine I reunited the two administrative divisions of the Empire as sole Augustus. The western part collapsed in the s while the eastern part ended with the capture of Constantinople Constantine introduced important changes into the Empire's military, monetary, civil and religious institutions.
As regards his economic policies in particular, he has been accused by certain scholars of "reckless fiscality", but the gold solidus he introduced became a stable currency that transformed the economy and promoted development. Constantine established the principle that emperors could not settle questions of doctrine on their own, but should summon instead general ecclesiastical councils for that purpose.
His convening of both the Synod of Arles and the First Council of Nicaea indicated his interest in the unity of the Church, and showcased his claim to be its head.
In and he issued a series of edicts essentially banning pagan religion. Pagan festivals and sacrifices were banned, as was access to all pagan temples and places of worship.
Arcadius in the East and Honorius in the West, once again dividing Imperial administration. In the 5th century the Eastern part of the empire was largely spared the difficulties faced by the West—due in part to a more established urban culture and greater financial resources, which allowed it to placate invaders with tribute and pay foreign mercenaries.
This success allowed Theodosius II to focus on the codification of Roman law and further fortification of the walls of Constantinoplewhich left the city impervious to most attacks until To fend off the HunsTheodosius had to pay an enormous annual tribute to Attila.
His successor, Marcianrefused to continue to pay the tribute, but Attila had already diverted his attention to the West. After Attila's death inthe Hun Empire collapsed, and many of the remaining Huns were often hired as mercenaries by Constantinople. Odoacer, now ruler of Italy, was nominally Zeno's subordinate but acted with complete autonomy, eventually providing support to a rebellion against the Emperor.
By urging Theodoric to conquer Italy, Zeno rid the Eastern Empire of an unruly subordinate Odoacer and moved another Theodoric further from the heart of the Empire.
After Odoacer's defeat inTheodoric ruled Italy de facto, although he was never recognised by the eastern emperors as "king" rex.PERIOD 3 REVIEW: Whereas Europe was not a major civilization area before CE, by it was connected to major trade routes, Social, cultural, economic patterns in the Amerindian world - Major civilizations emerged, building on the base of smaller, less powerful groups from the previous era.

AP WORLD HISTORY: Post-Classical World ( TO CE) Nature and causes of changes in the world history framework leading up to their attacks at first disrupted the major trade routes, their rule eventually brought the Pax Mongolica, or a peace often compared to the Pax Romana established in ancient.
Post-classical history (also called the Post-Antiquity era, Post-Ancient Era, or Pre-Modern Era) is a periodization commonly used by the school of "world history" instead of Middle Ages (Medieval), which is roughly synonymous. The trade routes were the communications highways of the ancient world.
New inventions, religious beliefs, artistic styles, languages, and social customs, as well as goods and raw materials, were transmitted by people moving from one . It brought us the major civilizations, religions, and trade routes.
But, what happens when all of the major world powers collapse? This is the Post-Classical era.
